Reuben Casserole


To make this delightful Reuben casserole, you'll need the following ingredients. We've also included some healthy alternatives to make this dish even better for you.

  • 2 cups of sauerkraut (rinsed and drained)
  • 1 pound of lean corned beef (cut into bite-sized pieces)
  • 2 cups of shredded Swiss cheese
  • 1 cup of Greek yogurt (a healthy alternative to mayonnaise)
  • 1/2 cup of low-fat sour cream
  • 2 tablespoons of Dijon mustard
  • 1 tablespoon of prepared horseradish (optional)
  • 4 slices of whole-grain bread (cubed)
  • 1 tablespoon of olive oil (for toasting bread cubes)
  • Salt and pepper (to taste)

Preparation Steps

Step 1: Preheat and Prepare

  • Preheat your oven to 375°F (190°C).
  • Lightly grease a 9x13-inch baking dish to prevent sticking.

Step 2: Prepare the Sauerkraut Layer

  • Spread the rinsed and drained sauerkraut evenly over the bottom of the baking dish.

Step 3: Add the Corned Beef

  • Evenly distribute the bite-sized corned beef pieces over the sauerkraut layer.

Step 4: Mix the Cheese Mixture

  • In a mixing bowl, combine the shredded Swiss cheese, Greek yogurt, low-fat sour cream, Dijon mustard, and horseradish (if using).
  • Mix well until combined and smooth.

Step 5: Layer the Cheese Mixture

  • Spoon the cheese mixture over the corned beef, spreading it out evenly to cover the entire dish.

Step 6: Prepare the Bread Cubes

  • In a skillet, heat the olive oil over medium heat.
  • Add the cubed whole-grain bread and toast until golden brown and crisp, stirring occasionally.
  • Evenly sprinkle the toasted bread cubes over the cheese mixture.

Step 7: Bake

  • Place the casserole in the preheated oven and bake for about 25-30 minutes, or until the top is bubbly and golden brown.
  • Remove from the oven and allow it to cool for a few minutes before serving.

Tips for a Kid-Friendly Version

  • Reduce the tanginess by using less sauerkraut or substituting with finely shredded cabbage sautéed with a touch of vinegar.
  • Add a layer of thinly sliced potatoes to create a familiar texture and flavor that kids love.
  • Incorporate mild cheese if Swiss is too strong for young palates. Mozzarella or mild cheddar can be great substitutes.

Serving Suggestions

To create a well-rounded meal, consider serving your Reuben casserole with:

  • Steamed vegetables like broccoli or green beans for added vitamins and minerals.
  • A fresh side salad with a light vinaigrette to balance the richness of the casserole.
  • Roasted sweet potatoes for a healthy and comforting side dish.
